That's a sobering fact. It is good to keep in mind that this business whose name evolved from AGW , to just Global Warming, and then rather absurdly to "Climate Change". Has nothing to do with climate change, nor whether mankind is messing up the global climate -- which is a separate question. It still has only to do with the Hansen Hypothesis. And that hypothesis has to my satisfaction been proven wrong.Remember the planet has been cooling since the time of accretion.
My point is this, we wouldn't be trying to get international agreement on CO2 emission if it weren't that we were still stuck on the Hansen Hypothesis, and if it weren't being assumed that Hansen's hypothesis is correct; this, despite the now massive amount of data that's calling Hansen's hypothesis into question. So why are we doing this? And why are we insisting on calling AGW "climate change?" The climate changes regardless of whether Hansen's hypothesis is correct?
I think one has to look in the political/financial realm for the answer to these questions. I least I hope so, because otherwise it is far too depressing to consider that the answers might turn out to be the same as the answer to the question, "why did we wait half a century to start turning right on red?", or the question, "Why are we still sitting at red lights despite there not being another car in sight for miles in all possible approaching directions?"
